U.S.-Vietnam Cooperative Research in Simulation Studies of Strongly Interacting, Disordered Electronic Systems

9903843该奖项支持明尼苏达大学和威斯康星大学与越南河内国立大学、越南国家自然科学技术中心和河内工业大学在两种相关电子系统(稀土磁体和半导体量子点)研究方面的初步合作。这项拟议的研究是1998年1月在河内举行的科学技术周期间讨论的结果，部分得到了国家科学基金会的支持。越南已经在稀土永磁体领域建立了研究实力，这是越南的一个重要领域，拥有丰富的稀土储量。越南在这一领域的实验工作与通过合作提供的建模支持相结合，有望成为互惠互利的研究伙伴关系。关于量子点的工作与一个相当感兴趣的领域有关，即简单的随机矩阵理论模型无法预测无序量子点的能级结构。越南科学家在建模方面有经验，这将补充美国团队的方法，并将有助于理解这个问题，这是目前纳米结构基础实验研究的大部分基础。

9903843HalleyThis award supports initial stages of collaboration on study of two types of correlated electron systems, rare earth magnets and semiconductor quantum dots, between the Universities of Minnesota and Wisconsin, and Vietnam National University, Hanoi; the National Center for Natural Science and Technology, Vietnam; and the Technical University of Hanoi. The proposed research is an outgrowth of discussions held in Hanoi January 1998 during the Science and Technology Week, partially supported by NSF.The Vietnamese have already established research strength in the area of rare earth permanent magnets, an important area for Vietnam, which has significant rare earth reserves. The combination of the Vietnamese experimental work in this area with the modeling support available through the collaboration is promising for a mutually beneficial research partnership. The work on quantum dots is relevant to an area of considerable interest, the failure of the simple random matrix theory model to predict the energy level structure of disordered quantum dots. Vietnamese scientists have experience in modeling that will complement the approach of the US team and will contribute to understanding this problem, which underlies much of the current fundamental experimental research in nanostructures.
